File names
●
The only files that can be recognized as MP3/WMA and played are those with
the extension .mp3 or .wma.
ID3 and WMA tags
●
ID3 tags can be added to MP3 files, making it possible to record the track title,
artist name, etc.
The system is compatible with ID3 Ver. 1.0, 1.1, and Ver. 2.2, 2.3, 2.4 ID3 tags. (The
number of characters is based on ID3 Ver. 1.0 and 1.1.)
WMA tags can be added to WMA files, making it possible to record the track title
and artist name in the same way as with ID3 tags.
MP3 and WMA playback
●
• When a device containing MP3 or WMA files is connected, all files in the USB
memory device are checked. Once the file check is finished, the first MP3 or
WMA file is played. To make the file check finish more quickly, we recommend
that you do not include any files other than MP3 or WMA files or create any
unnecessary folders.
• When the USB device is connected and the audio source is changed to USB
memory mode, the USB device will start playing the first file in the first folder. If
the same device is removed and reinserted (and the contents have not been
changed), the USB device will resume play from the same point in which it was
last used.
Extensions
●
If the file extensions .mp3 and .wma are used for files other than MP3 and WMA
files, they will be skipped (not played).
Playback
●
• To play MP3 files with steady sound quality, we recommend a fixed bit rate of at
least 128 kbps and a sampling frequency of 44.1 kHz.
• There is a wide variety of freeware and other encoding software for MP3 and
WMA files on the market, and depending on the status of the encoding and the
file format, poor sound quality or noise at the start of playback may result. In
some cases, playback may not be possible at all.
